Re: Righting a SC15, Parts, and Repairing

Bill, I have the utmost respect for you. The Chesapeake Bay has some of the nastiest chop on the entire east coast, there are tons of shipwrecks to attest to that. I have pitch poled, full barrel rolled (mast pointing straight at the bottom, more than once), got flattened by a micro down burst, caug...

Re: Righting a SC15, Parts, and Repairing

Bill, You weren't there. I always, every single time climbed up and opened the lever and extended the shroud on the high hull. I have witnesses. The system is flawed, lots and lots of things can go fubar at any time. DO NOT TELL ME WHAT I DID WRONG. I was there and I know exactly what happened and w...

Re: Righting a SC15, Parts, and Repairing

Roger that Bill, You are correct saying that my mind is made up. You just confirmed that "when done improperly" things can break, also true. If a thing can get FUBAR'ed, it WILL get FUBAR'ed that is Murphy's law in action. In my case I had angels on board cause I never broke anything and the boat is...

Re: Righting a SC15, Parts, and Repairing

ah...... sounds easy I must be a caveman..... never in big chop with the mast bouncing to hell and gone pulling on the stay was I able to align three 5/16 inch holes and then stuff a 5/16 inch quick pin through the three holes before the next wave ripped the three holes out of alignment. Sorry bill,...

Re: Righting a SC15, Parts, and Repairing

continue explaining bill please note that the original poster asked how to do this when SOLO explain how a solo sailor holds the helm, drives the boat, traps out to windward and simultaneously re-pins the slack leeward shroud. it is the struggle to re-pin the stay WHEN SOLO IN BIG CHOP AND BIG AIR t...

Re: Righting a SC15, Parts, and Repairing

hopefully more members will chime in with their thoughts on the righting subject if you plan to use the hyfield lever and extend one side stay be sure that you have pinned the mast base at the rotation ball before sailing away from the shore. (this is a rigging oversight that everyone makes occasion...

Re: Righting a SC15, Parts, and Repairing

Braeden910, If solo do not use the hyfield lever and slack the side stay, you will never get the side stay re-pinned when sailing solo. can give more description why later. Option 2: read up on righting bags, buy one, carry it at all times, rig your boat with the proper lines for this bag, practice ...

Re: spinnaker, CE, and attitude

Bill, where do I send the tuition money? :D Thanks for the great load path description. Does the vertical force coming from the head sail reduce the compression forces in the mast? Thanks again, that was a great read on the loads in compression.

Re: spinnaker, CE, and attitude

Bill, I hope you are enjoying this conversation, I certainly am! I'd like to understand mast compression loads a lot better. I understand a bit of the Euler slender column stuff, but not how the sails create more compression in the column as they load up. Maybe the hint is in your post about the mai...

Re: spinnaker, CE, and attitude

Okay so I made my model today, using a flat plate for SA and the centroid of the flat plate for the CE. I constructed the model so that I can change the angles of the three major variables, heel angle, sheeting angle and the luff angle. Here are my conclusions (possibly still wrong) but what I see i...

Re: spinnaker, CE, and attitude

Thanks again. Are the three component forces described as pitch, yaw and roll. I think I'll make a little model to better visualize the situation as the boat heels. I framed houses as a young man, the boss was always screaming, plumb, level, square and straight, referencing a similar coordinate syst...

Re: spinnaker, CE, and attitude

Where the sail curves around at the luff, combined with the rake angle from bow to mast, there will be some perpendicular vector lines coming off the sail that have a component of vertical. Am I understanding that correctly? Thanks Bill, for helping me visualize this.

spinnaker, CE, and attitude

Bill, your thoughts and related theory please. When you deploy a fore sail such as an asymmetric spinnaker or a screecher, does the movement of the CE of the entire sail plan add a force pressing the bows deeper or a lift component that pulls the bows up? or is it neutral? I don't own either of thes...

Re: going rogue..........

havliii, Back to your CE Question. Ans: Shorten the foot of your main sail and add s square top. Bill, many thanks for all the advice and the education over the years. Of course your advice was spot on, greatly appreciated. I did as you suggested. Bought a square top with a shorter foot, bought a b...
